Abstract

A powder composite core is to be particularly dense and strong while being produced from soft magnetic alloys. In particular, the expansion of the heat-treated core is to be avoided. To produce this core, a strip of a soft magnetic alloy is first comminuted to form particles. The particles are mixed with a first binder having a curing temperature T1,cure and a decomposition temperature T1,decompose and a second binder having a curing temperature T2,cure and a decomposition temperature T2,decompose, wherein T1,cure < T2,cure <= T1,decompose < T2,decompose. The mix is pressed to produce a magnet core while the first binder is cured. The magnet core is then subjected to a heat treatment accompanied by the curing of the second binder at a heat treatment temperature TAnneal > T2,cure.
